If someone says that socks need to match, they are wrong. I knit these with my favourite cheap acrylic yarn Satu with 4mm needles. My pathetic little "balcony" (basicly just a door ventilate my apartment) is for some reason my favourite place to photograph socks.
Pretty cool pajama pants, aren't they? I bought them for myself as a birthday present. There are bats in them, and the eyes and teeth of the bats glow in the dark. Sweeeet!
